[Formation by the mycoheptin producer of aureothin and pentaene 2814-P, separated into its mycopentene-1 and mycopentene-2 components].

Aureothin, a toxic substance of non-polyenic nature and pentaen 2814-P were isolated from the metabolites of Streptoverticillium mycoheptinicum, the organism producing mycoheptaine. The above substances are also produced by other actinomycetes. The pentaenic antibiotic was divided into 2 components. Physico-chemical and biological properties, as well as the composition of the substances were studied.
